Duplicate code is one of the most pungent code smells. A rule that is often used is to re-structure code once it is duplicated in three or more places.
Common duplication problems, and corresponding solutions are:
| 1 | <?php |
||
| 9 | trait ApiChannelTrait |
||
| 10 | { |
||
| 11 | /** |
||
| 12 | * @param Request $request |
||
| 13 | * @return mixed |
||
| 14 | */ |
||
| 15 | abstract function dispatch(Request $request); |
||
| 16 | |||
| 17 | /** |
||
| 18 | * @override |
||
| 19 | * @inheritDoc |
||
| 20 | */ |
||
| 21 | public function pSubscribe(...$patterns) |
||
| 29 | |||
| 30 | /** |
||
| 31 | * @override |
||
| 32 | * @inheritDoc |
||
| 33 | */ |
||
| 34 | public function pubSub($command, array $args = []) |
||
| 41 | |||
| 42 | /** |
||
| 43 | * @override |
||
| 44 | * @inheritDoc |
||
| 45 | */ |
||
| 46 | View Code Duplication | public function publish($channel, $message) |
|
| 54 | |||
| 55 | /** |
||
| 56 | * @override |
||
| 57 | * @inheritDoc |
||
| 58 | */ |
||
| 59 | public function pUnsubscribe(...$patterns) |
||
| 67 | |||
| 68 | /** |
||
| 69 | * @override |
||
| 70 | * @inheritDoc |
||
| 71 | */ |
||
| 72 | public function unSubscribe(...$channels) |
||
| 80 | |||
| 81 | /** |
||
| 82 | * @override |
||
| 83 | * @inheritDoc |
||
| 84 | */ |
||
| 85 | public function subscribe(...$channels) |
||
| 93 | } |
Adding explicit visibility (
private,protected, orpublic) is generally recommend to communicate to other developers how, and from where this method is intended to be used.
